Lean Six Sigma Certification: Professional vs. University

Lean Six Sigma certifications offer a structured way to validate expertise and proficiency in this specialized domain. Depending on your career aspirations and industry demand, you can choose between two primary types of certifications: Professional and University-based.

Professional Certification: To secure a professional certification, one must pass an exam from an institution recognized in this field. Renowned bodies such as ASQ (American Society for Quality) and IASSC (International Association for Six Sigma Certification) offer these certifications. Notably, when selecting Lean Six Sigma courses, ensure they align with the syllabi of these recognized exams. It’s crucial to understand the varied prerequisites for different certifications. For instance, to attempt the ASQ Green Belt Certification, a candidate must have 3 years of professional experience on a Six Sigma project. In contrast, the IASSC does not mandate any prior experience.

University Certification: University-level certifications are another viable option. They hold relevance across numerous industries and offer academic rigor combined with practical insights. However, before embarking on this route, it’s advisable to consult with your employer and peers to determine the most fitting certification for your specific objectives.

In conclusion, whether you opt for professional or university certification, your decision should align with your career goals, industry demands, and the value a particular certificate holds in your domain.
